  • Page 19 A carrier-to-noise measurement can be made very simply by using Example 5. Make a the delta-marker function. This can be demonstrated by using the carrier-to-noise calibrator signal, placing a marker at the peak of the signal, then measurement placing a delta marker somewhere in the noise. The carrier-to-noise measurement result is displayed in the active function area and is normalized to a 1 Hz bandwidth.
  • Page 20 Pressing NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN turns on the marker-noise function. MKNOISE On Off The spectrum analyzer enables sample detection mode and performs a digital average for 16 bits around the active marker. The marker readout in the active function area on the display reads out the di erence between the markers in dBc/1 Hz.
